The Safer Neighbourhoods Partnership, along with Neighbourhood Watch, has issued advice to prevent people, their homes and vehicles from being targeted by thieves.
Officers are urging people to park in well-lit areas or places with CCTV coverage, to deter opportunist criminals, and never to leave presents on show in vehicles.
Presents should be kept out of sight at home and larger items such as bicycles stored in sheds or secure outbuildings.
Empty gift boxes should never be left outside properties as this can advertise new goods.
Partygoers on nights are encouraged to drink responsibly and, if possible, arrange for at least one member of a group to stay sober, in order to keep an eye on others.
And when seeking taxis at the end of the night, people are urged to always use a taxi or licensed minicab (Hackney Carriage), pre-booking where possible.
Mobile phones should always be carried in case of emergencies.
Chief Inspector Phil Ward said the aim was to ensure the public enjoyed a safe Christmas without the fear of becoming victims of crime.
He added: “Our officers are out and about in key locations as part of Operation Lancers in order to target those individuals who may look to target shoppers or their vehicles at this time of year.
“As ever neighbourhood policing teams across North Lincolnshire will be providing a high visibility deterrent to those looking to commit crime but we can’t tackle crime alone.
“Following just some of the tips we have released could make all the difference and ensure you are able to remember this Christmas for all the right reasons.”
